Container orchestration, pod management, cluster architecture, and everything K8s.
Let me be direct with you: most Kubernetes clusters I audit are hemorrhaging money because of poorly configured resource requests. I've seen teams running...
How to use Istio's built-in observability — distributed tracing with Jaeger, Prometheus metrics, Kiali service graph — and enforce zero-trust access control with AuthorizationPolicies.
A practical guide to getting started with Istio — installing on Kubernetes, enabling automatic mTLS, configuring VirtualServices for traffic management, and understanding the sidecar injection model.
Fix the Helm 'UPGRADE FAILED: has no deployed releases' error when a previous install failed and left the release in a broken state.
Clean up Kubernetes evicted pods and fix the underlying disk pressure or resource exhaustion that causes pod evictions.
Resolve ImagePullBackOff and ErrImagePull errors in Kubernetes — fix registry credentials, image tags, and network access issues.
Diagnose and fix OOMKilled errors in Kubernetes pods — understand memory limits, identify leaks, and configure resource requests correctly.
A hands-on guide to deploying and operating Kafka on Kubernetes using the Strimzi operator — covering cluster config, topic management, and TLS security.
How to implement zero-trust pod-to-pod communication in Kubernetes using NetworkPolicies — deny by default, allow explicitly, and validate it works.
A comprehensive guide to every Kubernetes deployment strategy — rolling updates, blue-green, canary, and progressive delivery with Argo Rollouts and Flagger.
A practical comparison of Kubernetes Ingress and Gateway API, with a migration strategy that won't take down your production traffic.
A deep dive into Kubernetes resource requests, limits, QoS classes, and why getting them wrong leads to OOM kills, throttling, and wasted money.
How to configure encryption at rest for Kubernetes secrets using KMS providers, because your secrets in etcd are stored in plaintext by default.
A systematic approach to debugging CrashLoopBackOff in Kubernetes, covering the most common causes and the exact commands to diagnose each one.
How to configure Kubernetes HPA with Prometheus custom metrics so your workloads scale on what actually matters — not just CPU and memory.
How to implement zero-trust networking in Kubernetes using NetworkPolicies — deny by default, allow by exception, and sleep better at night.
The kubectl quick reference — organized by task with copy-paste ready commands for pods, deployments, services, debugging, and more.
Learn everything about Kubernetes Pod Security Standards (PSS) and Pod Security Admission (PSA) — from baseline to restricted profiles with practical examples.
Battle-tested patterns for writing Helm charts that survive production — covering values design, template structure, lifecycle hooks, and chart testing.
